How many units (kWh) does a electric geyser use per month?

Running 2 hours a day at 2,000 W, a electric geyser consumes about 120 units per month — that's 4.0 units per day.

How much does it cost per month on the 200-unit slab?

On the Unprotected 101–200 unit slab (Rs. 22.95/unit) the energy charge alone is about Rs. 2754. Add ~Rs. 360 for FPA + QTA and 18% GST on top.

Is a electric geyser cheaper to run on protected tariff?

Yes — at Rs. 11.69/unit (protected slab 1–100 units) the same 120 units cost only Rs. 1403, roughly half. But qualifying requires staying under 200 units total for 6 months, which is hard when this appliance alone uses 120 units.

Does running it during off-peak hours save money?

Only if you have a Time-of-Use (TOU) meter — typically 3-phase domestic, commercial A-2 or industrial B-2. On a flat single-phase domestic meter the tariff is the same 24 hours. See your DISCO's peak-hours page for exact windows.

Will solar make this appliance free to run?

Solar cuts the daytime portion of this load to nearly zero. Under the 2026 net-billing regime, exported units are worth Rs. 11–13 vs Rs. 27–42 for units you self-consume — so timing the appliance to run in daylight matters far more than it did on old net-metering.

Electric geyser running cost in Pakistan (2026)

A 55-litre electric geyser has a 2 kW element that runs whenever the thermostat calls for heat — typically 2 hours a day in winter. Expect Rs. 2,000–7,000 per month during the coldest months.

How much energy does a electric geyser use?

Timeframe	Energy used	Notes
Per hour	2.00 kWh	Steady-state draw
Per day	4.00 kWh	2 hours of runtime
Per month	120 kWh	Full month at daily duty cycle
Per year	720 kWh	6-month season

Cost per slab — NEPRA Unprotected Residential (FY 2025–26)

Slab	Rs./unit	Per hour	Per day	Per month
1–100 units	16.48	Rs. 32.96	Rs. 66	Rs. 1978
101–200 units	22.95	Rs. 45.90	Rs. 92	Rs. 2754

Energy charge only. Add ~Rs. 360/month for FPA + QTA at typical rates, then 18% GST on the total. Electricity duty and PTV fee are also stacked — see the full electricity bill calculator for the complete tax pass-through.

Protected consumers (≤200 units, 6-month rule)

Slab	Rs./unit	Per month cost
1–100 units	11.69	Rs. 1403
101–200 units	14.16	Rs. 1699

Check your Protected consumer eligibility — the ≤200 unit rule is strict and one bad month resets the 6-month counter.

Cut the running cost

Set the thermostat to 55°C, not 70°C — you save ~20% and 55°C is still safe for a hot shower.
Wrap the tank and the first 2 m of the hot-water pipe in insulation jackets.
Run the geyser only 45 minutes before bath time — leaving it on standby all day doubles the kWh.
In gas-served areas (SNGPL/SSGC), a gas geyser is 4–6× cheaper per litre of hot water.

Fine print

Instant electric geysers pull 4.5–8 kW but only for a few minutes per shower; the total daily energy is similar for the same hot-water volume.
